BASIC FUNCTION BLOCKS
The M37920S4CGP is the same functions as the M37920F8CGP
except for the following.
Therefore, refer to the datasheet of the M37920F8CGP.
The M37920S4CGP does not include the internal flash memory.
The M37920S4CGP operates only in the microprocessor mode.
The M37920S4CGP does not have the flash memory control regis-
ter (address 9E
16
).
Some of programmable I/O ports of the M37920S4CGP differ from
those of the M37920FGCGP.
